JOB DESCRIPTION

APPLY
Are you passionate about High Performance Computing* Are you interested in helping to architect some of the largest computing and storage systems anywhere in the world*



The Advanced Technologies Group (ATG) at the National Energy Research Scientific Computing Center (NERSC) is growing. NERSC, the primary scientific computing facility for the Office of Science in the U.S. Department of Energy (DOE), is a world leader in accelerating scientific discovery through computation, providing high performance computing, data storage and analysis tools and expertise to researchers.



In this role you will evaluate global technology trends and combine them with the needs of NERSC users with the goal of architecting the supercomputing ecosystem of the future. You will work with technology providers to influence their designs and provide input for HPC system procurements and DOE technology roadmaps beyond the next decade.



What you will do:

*

Assess emerging technologies in architecture, algorithms, parallel programming paradigms and languages to provide input for HPC system procurements and DOE technology roadmaps.
*

Evaluate hardware and software technologies in emerging areas, such as cloud computing and AI, for their potential to be applied to HPC.
*

Work with vendors to prioritize, develop and enhance their technologies in order to better meet the needs of DOE Office of Science application codes and workflows.
*

Measure and understand the performance and scalability of key scientific applications or workflows that comprise NERSC's evolving workload on current and future high performance computing (HPC) and data intensive platforms.
*

Develop techniques to assess the needs of the DOE workload in aggregate. Work to understand potential trade-offs and to match specific technologies to specific classes of applications as needed.
*

Prepare timely reports, papers, and lectures describing significant results for dissemination within NERSC and throughout the broader HPC research community.
*

Contribute performance-related expertise to cross-team NERSC activities that may involve application performance tuning, workflow optimization, interconnects, storage I/O, and/or data analysis functions.
*

Participate in extrapolation of technology trends over the next decade of HPC platforms.
*

Participate in the NERSC selection process for acquisition of next-generation HPC systems.

Additional Responsibilities:

*

Provide technical conceptual guidance to other group members and management, suggest directions for investigation, create new opportunities for NERSC, and serve as a principal collaborator on major projects.



What is Required:

*

B.S. degree in Computer Science, Computational Science, Computer Architecture, Physical or Biological sciences or equivalent experience and a minimum of eight (8) years experience in hardware and/or software development for HPC systems and/or technologies.
*

Detailed understanding of state-of-the-art tools used to program, profile, and debug parallel scientific applications & workflows such as MPI, PGAS, OpenMP, and hybrid-parallel codes using C, C++, Python, and Fortran code.
*

Experience in benchmarking, code instrumentation, and performance analysis of parallel applications & workflows with emphasis on emerging architectures.
*

Experience with performance profiling tools, hardware performance counters (e.g. Intel Vtune, Cray PAT, or PAPI), and/or code instrumentation systems like Tau.
*

Experience with construction, porting and/or analysis of large-scale scientific applications to a variety of parallel HPC platforms.
*

Experience with computer architecture trends and their application to High Performance Computing (HPC).
*

A demonstrated ability to lead technical efforts in a team environment.
*

Demonstrated track record of research and technical publications. Ability to write and present technical papers at conferences and other venues to disseminate research work.

Desired Qualifications:

*

Masters or PhD degree in Computer Science, Computational Science, Computer Architecture or a related field.
*

Advanced expertise in using and/or developing modeling and simulation tools to project performance.
*

Nationally and or internationally recognized expertise in an HPC related discipline.
*

In depth knowledge of HPC computer architecture technologies including CPU, memory, interconnect, parallel I/O and networking.
*

Experience with microbenchmarks and ability to write microbenchmarks that are able to exhibit the same performance characteristics as the full application code.

The posting shall remain open until the position is filled.

Notes:

*

This is a full-time career appointment, exempt (monthly paid) from overtime pay.
*

Classification will depend upon the applicant's level of skills, knowledge, and abilities.
*

This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
*

Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
